Most materials have been collected from original author.
Some scripts need to be collected, but will no longer run and can only be used to guide writing new executables.
Word lists used in the original experiment are saved in files (6_letters4.txt and 5_letters4noq.txt).
As noted by the original author:
"I wrote the experiments in C++ using a now defunct library. I still have the executables, but am unfortunately no longer able to run them. I'm happy to supply the executables and/or source code, but I don't think they would be of much use to you. If I were to replicate this study, I would re-implement it from scratch following the methods as described in the paper."
Executables are expected to be received soon, but must be rewritten.
